1st: Origin of Symmetry. Riffs, riffs, BASS! PIANO! It has everything. I love it, my favourite album for personal reasons.
2nd: The Resistance: Like Origin, for me there isn't a song where I think "ewww". It has some of Muse's best material to date.
3rd: Absolution: Great album, feels too long sometimes though, and I don't like some songs (like Endlessly)
Tied 4th place: Showbiz and BH&R: Showbiz has Overdue on it, which is god-awful.
BH&R has SP on it, which is just as awful. Both have their strong and weak points. I like them both.
